The present invention is related to a remote control device with displays and ball switches. More particularly, the invention relates to a remote control device with a plurality of functional switches which is capable of readily controlling all functions of an electronic machine using a wheel and ball switch from a remote location.
Also, the functions can be easily selected from a displayed menu system hence a separate learning process is not required.
Conventionally, a wireless remote control based on an Infrared light signal method was used in order to control an electronic machine remotely. Initially, these machines were confined to the type of machines such as TV, VCR and A/V, however, the application area is being enlarged comprising air conditioners and electric fans due to its proven convenience.
With the development of electronic technology, the number of functionality of various electronic machines has increased. As a result, the operation of remote control devices which control various electronic machines has become complicated and a significant time is required to understand the operation method. For the standard users, only the basic functions are being used and even for the skilled users the usage is limited due to their complexity.
“Directional key apparatus for a remote control device”, Korean Pat. Nos. 1997-8594(1997.03.14) discloses a remote control device which comprises a various type of menus for setting the environment of electronic machines based on cursor control rather than only providing the functions for switching on/off power and changing of channels.
The disclosed remote control device comprises a key body, a cap which covers and opens the key body, an upper section guide which unites with the cap at the lower face, a lower guide which unites with the upper guide and an elastic member which is placed between the key body and the upper guide and elastically supports the key body upwards, and a hook which forms along an extended line from the lower face of the key body through to the plate in order to prevent the derailing of a directional key.
This type of remote control devices has problem of requiring some time for accurate operation, due to the loss of directionality concerning the movement in up/down, left/right, up/left, up/right, down/left and down/right direction during the operation process of the key body to move the cursor.
Also, one remote control device for complicated functions and another remote control device for simple functions for an electronic machine were sometimes used, however, there were still problems of frequent movement to other keys and repeated button pushing.
Due to the inconvenience of using separate remote control device for each of different machines, an integrated remote control device was proposed. Four different types of remote control devices were proposed namely, A, B, C and D. A type is an integrated remote control device mainly for A/V machines which has 2 to 6 different types and has many switches. B type is also an integrated remote control device for all types of electronic machines and has many switches. C type is a small or card type integrated remote control device for A/V machines which has 2 to 6 different types and contains only the frequently used switches. D type is an integrated remote control device for all types of electronic machines which has a display device and a touch screen where it displays the corresponding switch configuration according to each of the machines and a selection can be made through the finger.
For the individual push switch type such as A, B, and C, the previously mentioned problems can not be solved. For D type, the problems with the number of switches and their functions can be resolved, however, the inconvenience of repeatedly pushing the buttons and not being able to feel the process of pushing the switch have been appeared as other problems.
In order to overcome the above problems of prior art, Korean Pat. Nos. 2000-47939(2000.08.18) issued to the same applicant of the present invention discloses a “Remote control device with displays and ball switches”.
The function selection ball switch which forms a part of the disclosed remote control device comprises a rotational axis which has a plurality of wheels at the both ends in order to restrict the moving direction of the ball, a plurality of fixture which support the rotational axis and a ball guide whose lower end is inserted to an inserting groove. The disclosed remote control device is practical easy to use, however, due to the increase in the number of parts, it has a higher manufacturing cost and the manufacturing time was longer.
The present invention is designed to overcome the above problems of prior art. The object of the invention is to provide a remote control device with displays and ball switches which enables a speedy control of all functions of an electronic machine possible through a wheel and ball switch by reducing the movement of fingers and can conveniently be used without a separate learning process by providing a displayed menu system where a selection can be made by a click.

As shown in
The machine name 18 and program name 19 in the first display area 20 can be scrolled up/down according to the rotation direction of the machine selection wheel switch section 6. The selected part in the middle is indicated by a shaded block.
Also, a matching number of arrows corresponding to the number of hidden machine name 19 and program name 18 are displayed at the top and bottom end of the display area in order to indicate to the user. In connection with this, the menu list of selected machines and programs are displayed in the second display area 23. In front of a selected program name 18, a start is displayed in order to be able to distinguish the machine name 19.
In the second display area 23, the menu name can be scrolled up/down according to the rotation direction of the menu selection wheel switch section 9. The selected part in the middle is indicated by a shaded block. Similarly to the first display area 20, a matching number of arrows corresponding to the number of hidden menu name is displayed at the top and bottom end of the second display area 23. The function of the function selection ball switch section 11 with respect to the selected menu indicated by a shaded block can also be display in third display area 24 at the same time.
The third display area 24 is switch on/off according to the rotation direction of the function selection ball switch section 9. By rotating the ball while depressing it, the menu advances 10 steps by one click.
Also, at the both ends of the third display area 24, an arrow indicating outwards is displayed in order to show that year and minutes are not being displayed (page 9, line 11).
The machine selection wheel switch section 6 and the function selection ball switch section 9 can perform the roles of up, down, rotation and push switches at one specific point and is almost identical to a wheel mouse.
The wheels 26, 27 of the machine and the function selection ball switch section 6, 9 are pushed towards the upper section or lower section, the first and second operation sections 4, 7 which are connected also rotates. The rotated amount is detected by the first and second click encoders 5, 8 and the detected electric signal is applied to CPU 12. More specifically, through the detected value of the first and second click encoders 5, 8, the program name, machine name, program list or menu display are scrolled to the shaded block by CPU 12.
In this instance, if the wheel is pressed the electric signals of the first and second push sensors 4 a, 7 a are applied to CPU 12. As a result, CPU 12 reads the control codes and transmits signals through the signal transmitting section 15 in order to operate the machines.
As shown in
The through-hole 28 a is formed in the middle of PCB 28 and at one side of the through-hole 28 a forms a hinge section 28 b as a single unit.
The click sound generation section 17 produces a click sound by the third to sixth click encoders 34-37 and simultaneously, according to the variation of detected electric signals produces a unique sound stored in the memory 12 through the control of CPU 12.
For example, the selection of unique sound according to the directions should be symbolically related to the direction of switch operation so that an upwards direction is a short high pitch note, a downwards direction is a short low pitch note, a left direction is a short high to low flow pitch, a right direction is a short low to high flow pitch and a pushing down direction is a long medium pitch.
Also, as shown in
As shown in
In this instance, when the selected contents are programs, a list of the programs is displayed in the second display area 23 and when the selected contents are machines, the menu of the machines are displayed. At the same time, the program selection or machine selection are displayed in the first display area 20 therefore the contents of the work in progress can more clearly be understood.
When the machine selection wheel switch section 6 is pressed, electric signals applied to CPU 12 by the first push sensor. If the content corresponding to the electric signals is a machine name 19, then the machine is switched on and if the content corresponding to the electric signals is a program name 18, then the machines are switched on according to the sequence of the list contents by transmitting the control signals through the signal transmitting section 15. Also, the machine name is moved to a shaded block in the first display area 20 in order to operate the next sequence.
As shown in
In this instance, a matching number of arrows corresponding to the number of hidden menu and at the time of first machine selection, the most frequently used menu is displayed in the shaded block.
According to the selected contents, the function of operational direction of the function selection ball switch section 11 is displayed in separate locations in the third display area 24. If there is a need to select according to the menu contents, then by pressing the menu selection wheel switch section 9, electric signals are applied to CPU 12 by the second pushing sensor 7 a and in turn CPU 12 transmits the signals via the signal transmitting section 15 in order to control the machine.
As shown in
In the fourth display area 25, the contents of the work which the function selection ball switch section 11 is capable of performing is displayed and the list of things that can be performed by pressing and rotating the function selection ball switch 11 in direction display icon of the function selection ball switch section 11.
If there is a need to select according to the function contents, then by pressing the function selection wheel switch section 11, electric signals are applied to CPU 12 by the third pushing sensor 40 and in turn CPU 12 transmits the signals via the signal transmitting section 15 in order to control the machine.
In this instance, the operation condition of the function selection ball switch section 11, if the ball 39 is pushed towards the direction as shown in
In this condition, the pushing direction of the ball 39 is changed to an upward direction, the rotation direction of ball 39 is restricted to a horizontal direction by the rotational axis 38 a, 38 c and subsequently rotation in the up and down directions are restricted.
More specifically, even if a user applies a force to the ball 39 in a slanted direction, the rotational axis 38 a, 38 b, 38 c, 38 d operate in specific ways in which an exact operation possible.
Also, electric signals are applied to CPU 12 by the fourth click encoder 35 located at the end of the rotational axis 38 b during the rotation of the ball 39.
By applying signals to CPU 12 by the fourth click encoder 35, CPU 12 recognizes that the ball 39 is moving upwards by comparing with the control codes and as previously mentioned, transmits signals through the signal transmitting section 15 in order to operate the machines.
Also, the unique sound from the memory 13, selected by CPU 12 as a result of electric signals from the fourth click encoder 35 can be sounded through the speaker of the click sound generation section 17.
Electric signals are applied to CPU 12 by the third push sensor 40 at the same when the ball 39 is pressed from top to bottom, hence, as mentioned previously, signals are transmitted through the signal transmitting section 15 in order to operate the machines.
Also, when a finger pressing the ball 39 is removed, the ball 39 returns to the center up position due to the elastic force of the third push sensor 40.
In the present invention, the function selection ball switch is used in a remote control device, however, it is apparent that it can be used in monitor picture control, car audio control, volume, timer, and color control for tv, home automations.
